Claims15
A segmented polyamide silicone block copolymer of Formula I
- wherein
- each * represents a point of attachment at the end of a repeat unit;
- each R1 is independently selected from alkylene, alkenylene, arylene, substituted arylene, heteroarylene, or substituted heteroarylene;
- each R2 is independently selected from dimer acid residue, alkene, alkylene, arylene, and heteroarylene, with the proviso that at least one R2 is dimer acid residue;
- each R3 is independently selected from covalent bond, alkylene, substituted alkylene, arylene, and substituted arylene;
- each R4 is independently N—R6;
- each R5 is independently selected from one or more silicone polymers and one or more polyethers, with the proviso that the one or more silicone polymers constitute at least 60% by weight of all R5 moieties;
- each R6 is independently selected from H and alkyl;
- each y is the independently from 1 to 1000;
- each x is independently from 2 to 200;
- n+m is from 2 to 1000;
- and
- m is no more than n/10.
